I am putting a Dell server together, more specifically R720. I have to select the correct Host Bus Adapter. This HBA on R710 will connect to a storage device. I am confused between these two:
QLogic 2562, Dual Port 8Gb Optical Fiber Channel HBA (price $2,045)
QLogic 8262, Dual Port 10Gb SFP+, Converged Network Adapter (price $1,618)
I thought since the QLogic 2562 is a fiber channel and is more expensive then it is faster in terms of IOPS. But, it is a 8Gb as opposed to 10 Gb of SFP+.
My questions:
Which one is better (IOPS performance, etc.)?
Why should I choose one over another?
